General CPP Metallized Film is a flexible packaging material produced by coating a thin layer of aluminum onto cast polypropylene (CPP) film through a vacuum metallizing process. This structure combines the natural flexibility of CPP with the enhanced barrier and visual properties of metallization, creating a practical solution for a wide range of packaging applications.
Compared with plain CPP film, the metallized version significantly improves moisture resistance, oxygen barrier performance, and light-blocking ability, while also delivering a premium metallic appearance. It is widely adopted in packaging structures that require a balance between protection, machinability, and cost efficiency.
Designed for modern flexible packaging systems, General CPP Metallized Film is suitable for lamination with other substrates such as BOPP, PET, and PE, making it an important functional layer in multi-layer packaging structures.
Enhanced Barrier Performance
The metallized layer effectively reduces moisture vapor and oxygen transmission, helping extend product shelf life and maintain freshness.
Excellent Flexibility
CPP base film provides strong softness and adaptability, making it suitable for high-speed packaging and lamination processes.
Uniform Metallized Surface
Stable vacuum coating ensures consistent appearance and performance across the entire roll.
Good Heat Resistance for Lamination
Supports thermal lamination processes without significant deformation or performance loss.
Premium Metallic Appearance
Provides a reflective surface that improves shelf impact and product visibility.
Strong Process Compatibility
Suitable for printing, slitting, laminating, and converting operations.

General CPP Metallized Film is widely used in flexible packaging industries where both barrier protection and visual appeal are required:
Food Packaging
Snack foods, biscuits, confectionery, and dry food packaging that require extended shelf life and aroma retention.
Flexible Lamination Structures
Used as a middle or outer layer in PET/CPP or BOPP/CPP composite films for improved barrier performance.
Pharmaceutical Packaging
Suitable for non-sensitive medicinal products requiring moisture protection.
Household Products Packaging
Detergent powders, wipes, and daily consumer goods packaging.
Industrial Packaging
Protective packaging for lightweight industrial components requiring moisture resistance.
In flexible packaging production, manufacturers often face limitations when using standard CPP or uncoated films:
Poor Barrier Performance
→ Metallized layer significantly improves protection against moisture and oxygen, reducing product spoilage risks.
Weak Shelf Presentation
→ Reflective metallic surface enhances visual impact and helps products stand out in retail environments.
Inconsistent Lamination Performance
→ Stable CPP base ensures smooth bonding with other substrates and reduces delamination risks.
High Material Costs in Multi-layer Structures
→ Functional metallized CPP can replace more expensive high-barrier materials in certain applications.
Processing Instability at High Speed
→ Excellent flexibility and dimensional stability support continuous production lines without frequent interruptions.
Balanced Performance Design
Combines barrier protection, flexibility, and machinability in one material.
Suitable for Mass Production
Stable roll quality ensures consistent results in large-scale industrial use.
Adaptable to Multiple Structures
Works well in both single-layer and laminated packaging systems.
Cost-Efficient Packaging Solution
Offers strong performance at a competitive material cost, making it ideal for bulk procurement.
Customizable Production Options
Film properties such as thickness, gloss level, and barrier strength can be adjusted based on end-use requirements.
Base Material: CPP is softer and more flexible; PET is stiffer with higher dimensional stability.
Barrier Performance: PET Metallized generally offers stronger oxygen and moisture barrier than CPP Metallized.
Processing: CPP is better for heat sealing and lamination flexibility; PET is preferred for high-speed printing and converting.
Application: CPP is widely used in snack and general flexible packaging; PET is used in premium packaging and high-barrier structures.
Cost: CPP is more cost-efficient; PET is relatively higher in price but offers stronger performance.
Advanced Metallizing Technology
Controlled vacuum deposition process ensures uniform aluminum layer distribution and stable performance.
